Volume goes up on it's own

When watching TV, the volume suddendly increased to over 60. I could not turn the volume down or turn the TV off with the remote. I manually turned off the TV and waited for a few seconds, when I turned the TV back on, the volume was still high. I turned it off again and unplugged it and let it sit for a few minutes. I turned it on and it is fine.
This is the second time it has happend in the last week. The TV is 4 years old. Is this an indicator that it is going to completely break down?

The fact it shows on tuner and not DVD means not likely a audio problem--check all audio settings in the set's menu AND if you are using a box for signal look there--has to be a setting.

Some JVC sets (brand indicated here) also had issues with when watching the background audio (like a sporting event) was louder than the people talking and could be interpreted as ringing--This is a setting in the set called something like "Theater" or "Hall"

yes direct into the buttons the WD40 is the best thing i've ever seen, that will not damage anything you can spray it without fear and then try to activate the buttons a few times, of course with the tv off.

If you use a digital cable box, it could be that the volume on that isn't turned up all the way. I didn't even realize the box had volume controls until 2 years after I got it...makes a HUGE difference now

First, start by unplugging set to try to reset. Then make sure that all settings in audio menu are correct. Also look for stuck volume up button on set and on remote. Sometimes buttons get lodged under surrounding frame. Also try to push volume down button on tv and watch for display on tv to see any change. If when you release button volume increases by itself, remove batteries from remote to eliminate it as cause. If nothing you try works expect to replace main pcb. You can probably price it online with model number. Good luck, Russmann.

Some dust in the button to lower the volume on your TV or on your remote control might be causing it to think it's being pressed. Try playing around with it, pressing it hard so as to relieve it of any pressure on the inside.

i HAVE THE SAME TV, SEEMS LIKE THE LAMP IS OUT. BUT ONLY TWO YEARS USE? WOW. iVE HAD MINE FOR 3 YEARS WITH ATLEAST 6 HOURS PER DAY USE. WELL GOOD LUCK AND DONT LET A TECHNICIAN CHARGE YOU 200 FOR LABOR TO TAKE OUT A FEW SCREWS
